A massive rogue roaming our galaxy may be a black hole
Alternatively, this unseen wanderer might be a hefty neutron star. Whatever it is, its gravity caused starlight to be warped — and that gave it away.

Explainer: Calculating a star’s age
Scientists can figure out a star's mass or composition pretty easily. Determining how old that star is, however, is a lot harder.

Exploding neutron star proves to be energy standout of the cosmos
This is what scientists had suspected. But until one showed up outside our galaxy, they couldn’t be sure. Now they are.
